THE CEMBRAN PINE 159 



Russia. The seeds also yield the " cedar " oil. To 

 obtain it the kernels are extracted from the seed, the 

 husk being stripped off, and ground into a powder. 

 The powder is put into pots covered with water, and 

 placed in slightly heated stoves. The oil from the 

 seed rises to the surface and is poured off into vessels 

 ready for use. 



It has been necessary to glance briefly at this trade 

 in the seed of the cembran pine since it naturally 

 affects the exploitation of the forests of this species 

 as also the felling arrangements in mixed forests 

 containing this pine in any abundance. A tree which 

 has a value other than for its timber alone owing to 

 the fact that it produces a minor product of marketable 

 value in addition to the major one — timber — must 

 necessarily be subject to a different form of treatment 

 to that applicable to the purely timber-yielding 

 species. And this fact has to be borne in mind when 

 considering the exploitation of the Pinus cembra 

 woods of Siberia and their possibilities as regards 

 supplying material to the timber markets of Europe.
